The EM101 is a small plastic-bodied electro-magnetic
flow meter, in nominal sizes 1/4”, 3/8” and
1/2”. Capable of measuring the pulsating flows from
air and solenoid-driven metering pumps, the meter is primarily
designed for electrically-conductive chemicals. In addition
to measuring and displaying flow rate and total flow,
this unit has a variety of outputs. For continuous transmission
of a flow signal, there is a 4-20 mA, and 0-5 volt signal,
and a frequency signal proportional to flow. In addition,
there are relay alarm outputs for low and high flows with
user-set flow levels.
